分体信息互联模式下的车辆轨迹数据采集方法

Vehicle Trajectory Data Acquisition Method based on the Split Information Interconnection Mode

基于现有移动车载交通数据采集设备都是由汽车改装成的专用检测车辆,价格昂贵、数据处理方法传统、时效性差的不足。论文旨在车辆上搭载一种常使用的具有数据传感及信息互联功能的智能设备(如智能手机),搭建独立于车辆的数据采集、交互及预处理系统,为交通流分析提供所需的车辆轨迹大数据集。本系统不同于专门的OBD设备,可充分利用已淘汰智能终端内的传感器功能,且成本低廉,还是一个可不断扩展开放平台,具有可持续开发特征,是一种创新的数字化赋能方法。

The existing mobile vehicle traffic data acquisition equipment,which are all special detection vehicles modified from automobiles,is expensive,the data processing methods are traditional,and the timeliness is poor.The purpose of this paper is to equip the vehicle with a commonly used intelligent device(such as a smart phone)with data sensing and information interconnection functions,and build a data collection,interaction and pre-processing system independent of the vehicle,so as to provide the required vehicle trajectory big data set for traffic flow analysis.This system is different from specialized OBD equipment,which can make full use of the sensor functions in the obsolete smart terminals,and is low-cost,and it is also an open platform that can be continuously expanded,with sustainable development characteristics,and is an innovative digital empowerment method.
